The Seagate Momentus 7200.2 160GB SATA Hard Drive model ST9160823ASG offers strong performance for a 2.5" form factor drive, and manages to do so while remaining cool and quiet. The testing portion of the review confirmed the performance and low temperature operation, but what has not yet been mentioned is that the drive is very quiet. The specifications indicate that it produces between 2.5 and 2.9 bels between idle and load, and although that might not mean much to many people out there, it translates to whisper quiet.
